BY M40112 n MWZSMQ 3,034,360 GRAIN AND MATERIAL SAMPLER Delmar L. Hampl,706 Margaret, Russell, Kans. Filed July 16, 1959, Ser. No. 827,550Claims. (Cl. 73-425) This invention relates to new and usefulimprovements in grain, etc., samplers and has for its primary objcct'toprovide, in a manner as hereinafter set forth, a device of thischaracter comprising novel means for discharging the sample.

Another very important object of the present invention is to provide, ina grain and material sampler of the aforementioned character comprisinga tube having therein a port controlled by a reciprocating valve, uniquemeans for actuating said valve.

Other objects of the invention are to provide a sampler of the characterdescribed which will be comparatively simple in construction, strong,durable, compact, of light weight and which maybe manufactured at lowcost.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawing forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 1 is a view principally in side elevation and partially inlongitudinal section of a sampler constructed in accordance with thepresent invention;

FIGURE 2 is an enlarged view principally in vertical longitudinalsection through the device;

FIGURE 3 is an end elevational view;

FIGURE 4 is a fragmentary view in longitudinal section through amodified form of the invention;

FIGURE 5 is a longitudinal sectional view through the forward end of thedevice, showing another modification; and,

FIGURE 6 is a fragmentary view in longitudinal section through theforward end portion of the device, showing another embodiment.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated in FIGURES l, 2and 3 of said drawing comprises a barrel or tube 7 of suitable metal orother material. Of course, the tube 7 may also be of any desired lengthand diameter. The forward or lower end of the tube 7 is closed byswaging or pinching, as indicated at 8. The rear end portion of the tube7 is bent, as indicated at 9, in a manner to provide a rearwardly anddownwardly inclined, pistol-type handle and discharge spout 10. Thelower end portion of the combination handle and spout 10 has formedtherein a notch or recess 11 the purpose of which will be presently setforth.

Formed in the top of the forward portion of the tube 7 is a port 12.Mounted for reciprocation in the tube 7 is a tubular control valve 13for the port 12.

The valve 13 is actuated through the medium of a metallic rod 14. Therod 14 includes a downwardly olfset forward end portion 15 which isfixed longitudinally in the valve 13. The rod 14 extends slidablythrough an opening 16 which is provided therefor in the bend 9 of thetube 7 and terminates in a generally U-shaped operating handle 17. Thehandle 17 comprises legs 18 and 19 which parallel the combination handleand spout 10. The bight portion 20 of the handle 17 is slidably. engagedin the notch 11. Thus, the handle 17 which, it will be observed,straddles the handle and spout 10, is retained against swinging movementrelatively thereto.

It is thought that the use or operation of the device will be readilyapparent from a consideration of the foregoing. Briefly, with the valve13 in closed position as shown in FIGURE 2 of the drawing, the tube 7 isnite States Patent 0 ICC Patented May 15, 1962 "valve 13 rearwardly toopen position as shown in FIG- URE l of the drawing thereby opening theport 12. The grain or material flows into the chamber 21 through theopen port 12, after which the valve 13 is again closed by pushing thehandle 17 forwardly until the leg 19 thereof abuts the combinationhandle and discharge spout 10. The device is then withdrawn from thegrain and swung upwardly and rearwardly for discharging the sample bygravity through the tubular valve 13 and the pouring spout 10. The spout10 also functions as a stop for limiting the travel of the handle 17 andconsequently the valve 13 in opposite directions.

In the modification of FIGURE 4 of the drawing, reference character 22designates a solid cylindrical valve for controlling the port-12. Inthis embodiment the rod 14 comprises a threaded forward end portion 23which is screwed into a centrally located socket 24 provided therefor inthe rear end portion of the valve 22.

In operation, the tube 7 is pushed into the grain with the valve 22 inclosed position. The valve 22 is then retracted to open position forpermitting the grain to enter the chamber 21 through the port 12. Thevalve 22 is then returned to closed position and the device with thesample in the chamber 21 is withdrawn from the grain. The device is theninverted and the valve 22 is again opened for discharging the samplethrough the port 12. In other respects this form of the invention issubstantially similar to the embodiment of FIGURE 1 of the drawing.

In the embodiment of FIGURE 5 of the drawing, the forward end of thetube 7 is closed through the medium vof a generally bullet-shaped plug25 of suitable metal. The plug 25 includes a reduced end portion 26which is plug of a suitable plastic which closes the forward end of thetube 7. The plug 29 is hollow and comprises an externally reduced rearportion 30 which is fixed in the tube 7.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly, all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.
